Unraveling Hydrocarbon Pool Boosted Propane Aromatization on Gallium/ZSM-5 Zeolite by Solid-State Nuclear Magnetic Resonance Spectroscopy

 Date:2021/10/15 12:59:38 Views:Times

A hydrocarbon pool process is revealed in propane aromatization over Ga/ZSM-5 zeolite. Cyclopentenyl cations are observed and determined as active intermediates in propane conversion by using solid-state NMR spectroscopy. The formation of cyclopentenyl cations initiates autocatalysis of propane to aromatics in the induction period. The aromatization process is promoted by hydride transfer between propane and cyclopentenyl cations.
